1 ZAP Cross Debuggers for STMicroelectronics Microcontrollers ZAP is a family of full-featured C and assembly language source-level debuggers designed to give STMicroelectronics embedded microcontroller developers a consistent and productive debugging environment across multiple target processors. Key Features: Provides a Portable Debugging Environment, Debugger for Each Stage of Your Project, Simulation and Real-Time options C and Assembler Source-level Debugging, ANSI C Debugging, Array and Structure Explorer, Debug Fully Optimized Code, Easy-to-use Graphical User Interface, Extensive Program Control & Analysis Features, Graphical Performance Analysis, Code and Data Coverage, C Level Trace, Robust Script language, Automated Testing, ZAP Gives You a Portable Debugging Environment Across Projects If you now use or are looking to design-in different STMicroelectronics microcontrollers into your embedded projects, ZAP helps you standardize your debugging tools across projects by giving you a portable graphical userinterface which helps improve developer productivity, saves expensive retraining costs and reduces product time-to-market pressures. ZAP is available for STMicroelectronics ST7 and ST7 Lite microcontroller families and across target debugging hardware. ZAP Addresses Your Debugging Needs At Each Stage of Your Project ZAP s multiple configurations are designed to address your debugging needs as your project moves from the design stage to final integration and test; ZAP configurations supported are: software simulation, target monitor, background debug mode, and in-circuit emulator. Each configuration gives you essentially the same user interface, thus vastly improving your productivity, but each addresses a different stage of your project. C and Assembler Source-level Debugging If your source code is written in C, you want to debug at the C level; if parts of your source code are written in assembly language you want to debug at the assembly language level. ZAP automatically supports both modes without any special options or settings, so you always see your original source code in the Source window. If you are debugging at the C level, you can activate a Disassembly window that shows you the corresponding assembly language code for each line of C source. ANSI C Debugging ZAP provides point and click access to any C object or construct including enums, bit fields, strings, doubles/floats, structures and stack frames. View objects and memory in various formats including character, binary, octal, hexadecimal, unsigned, ASCII and string formats. ZAP Debugs Fully Optimized C Code COSMIC C Compilers generate exactly the same code with and without the debug option, which means you can debug fully optimized C code and, once debugged using ZAP, your code is ready for PROM burning with no need to recompile. Debug information is never downloaded, FLASHED or PROMED into the target system. Page 1/5

2 Easy-to-use Graphical User-Interface ZAP is a full featured C and Assembly source level debugger interface available on PC for Windows 95/98/NT/2000 and XP. ZAP is an easy to use, intuitive debugging environment with a serious debugging engine incorporating over 15 years of embedded compiler and debugger technology. Zap includes all of the bells and whistles that desktop C programmers expect along with all of the low level features assembly language programmers need. ZAP s core technology along with it s look and feel are available for many different target processors and execution environments including Simulation, Development Kit (DVP), and in-circuit emulation (HDS). ZAP Main Window The main ZAP window acts like a desktop containing all of the display windows as well as all of the setup menus and status information. This window includes an optional button bar to control execution and displays. All of the buttons, menus and configuration are the same for all ZAPs except for the Target menu, which contains any target specific options and features such as Hardware breakpoints and emulator trace etc.. Source Window The Source window displays the source code for the loaded application and maintains the display during execution with the current Program counter. This window is color coded for C and Assembly keywords and optionally displays absolute addresses or code coverage information. You can double click on line numbers to set breakpoints, select variables for the monitor/watch window and single step the program. Page 2/5

ZAP Source-Level Debugger Product Description PC/Windows Host Disassembly Window The Disassembly window reads from the target s memory to provide an accurate disassembly of the actual programmed code.

3 ZAP Source-Level Debugger Product Description PC/Windows Host Disassembly Window The Disassembly window reads from the target s memory to provide an accurate disassembly of the actual programmed code. Colored highlights in the disassembly window are aligned with the source window to show the assembly instruction(s) corresponding to the highlighted lines in the source window. This window is useful when single stepping at the assembly level or tweaking the performance of the code. You also can double click on the addresses to set breakpoints. Register Window This window displays the internal CPU registers and allows you to modify the values by double clicking. The Simulator version of ZAP also includes two cycle accurate MCU counters. One displays the total number of cycles executed since the last reset and the second displays the number of cycles from the last execution command. Command Window The optional Command window is used to load command scripts or type any individual commands. The command window is useful for monitoring individual structure and array members as well as creating automated debugging sessions Stack window The Stack window displays a list of the functions in the current stack frame in the order they were called. It also displays the value of each function s arguments. This display provides a convenient way to follow execution through nested and recursive function calls. Monitor/Watch window The Monitor window is a scrollable window, which displays the values of monitored data objects and expressions. This window is updated each time the execution environment halts execution. You can double click on any variable to change its display format or update its value. Supported formats include: address of, character, binary, octal, decimal, unsigned, hexadecimal and string. Depending on the hardware used, ZAP also supports Real-Time Monitors that allow you to monitor and update variables and memory while the program is executing. Data window The Data window displays a block of target memory in a variety of formats including: disassembly, byte, word, long, binary, octal, decimal, hexadecimal and ASCII. You can change R/W memory simply by clicking on the value and typing the new value over the old. Changes in memory contents are highlighted to make it easy to track memory modifications as your program executes. Fill Memory This option allows you to fill memory between addresses with a specific or random pattern. The fill pattern can be a byte, word or long. Upload Data The data window can also be used to upload data from target memory to a text file. The data can be formatted as a data dump, disassembly or uploaded and converted to S-Records. This is useful for extracting an existing application from a target system. Source Browsing The source browser lets you search through the application s source files and double click on any function or file name to open multiple windows to let you view any source file in your application. You can also set breakpoints in any source browser window without changing the main source window. ZAP Configurations ZAP configurations define the code execution engines that ZAP uses to execute your application code. In general, each configuration is a separate application that provides full C and assembly language debugging. However, in some cases certain features are absent due to limitations in the target execution engine. For each target microcontroller supported by COSMIC products, there are at least two separate ZAP packages: (1) a remote, real-time debugger and (2) a hosted, non real-time simulator/debugger. All ZAP configurations include the standard windows described previously as well as the following features: Simulated I/O The simulated I/O feature is a very powerful feature that allows your application to interact with multiple data files located on the host system. This is typically achieved via a command script using watch points at PORT addresses along with special fopen, fread and fwrite ZAP commands. Automated Testing ZAP offers a robust high level command and scripting language which can be used to load multiple command scripts with multiple applications and perform any combination of ZAP commands without any user interaction. Save Layouts and Sessions This feature allows you to save a debugging session and play it back later. The save layout command saves the size and location of any open ZAP display windows. The save session command saves the layout, loaded application, source path and any monitor and data windows with their Page 3/5

Simulator Configuration (ZAP SIM) This configuration of ZAP provides an integrated cycle accurate instruction set simulator as the execution engine. Simulation is useful in the initial stages of your design, before you have access to target hardware, because it gives you a convenient way to debug algorithms and data structures before moving onto the more complicated hardware and software integration phase. You can also profile the execution of your code with the built in cycle accurate instruction timer to help you tune your application. The simulator configuration of ZAP is available for all target microcontrollers with Cosmic compiler support. ZAP SIM includes all of the standard ZAP features as well as the following additional features:: C and Assembly trace (non-real time) step backwards and forward through a recorded trace complete with recorded monitor values and register values. Interrupt Simulation - Simulate interrupt using the cycle accurate timer as a trigger mechanism or trigger on execution of an address. Graphical Performance Analysis ZAP SIM includes a performance analysis feature that displays cycles of execution on a file by-file or function-by-function basis. Double click on a function name or file name to display the number of times the function was called and the total number of cycles executed for that function. Performance information may also be saved as a text report. Code Coverage ZAP SIM s Code coverage feature displays information on executed source lines and address information. Choose to show all coverage, only code executed or only code not executed. Optional text report are available. Code coverage information can also be displayed in each source browser window by selecting show from the title bar. Variable Usage Reports ZAP SIM also includes a variable usage report feature that details global variable usage for each variable. ZAP totals the number and type of access for each variable. It also details each access to include the address of the instruction accessing the variable, the type of access (read or write) and the line number in the source file that performed the access. Chronograms Displays a graphical function call time-line for your application s functions. The Chronology information complete with enter and exit cycle counts can be saved in a text report for future use. Page 4/5
